MULTI TOUCH
TECHNOLOGY
ABSTRACT
When interacting with a regular
desktop computer, indirect devices such as a mouse or keyboard are used to
control the computer. Results of the interaction are displayed on a monitor.
Current operating systems are restricted to one pointing device. With the
introduction of multi-touch, a new form of human computer interaction is
introduced. Multi-touch combines display technology with sensors which are
capable of tracking multiple points of input. The idea is that this would allow
users to interact with the computer in a natural way.
Multi-touch
consists of a touch screen (screen, table, wall, etc.) or touchpad, as well as
a software that recognizes multiple simultaneous touch points, as opposed to
the standard touch screen which recognizes only one touch point at a time. Multi
touch using Frustrated Total Internal Reflection is a simple, inexpensive, and
scalable technique for enabling high-resolution multi- touch sensing on
rear-projected interactive surfaces. Different applications for multi-touch interfaces both
exist and are being proposed. Some uses
are individualistic eg iPhone, iPod touch, MacBook Pro, MacBook Air. The use of
multi-touch technology is expected to rapidly become common place.
